+#      This actually supports modular compilation, but the module overhead

+         This option provides a glob_match function for performing
+         simple text pattern matching.  It originated in the ATA code
+         to blacklist particular drive models, but other device drivers
+         may need similar functionality.
+
+         All drivers in the Linux kernel tree that require this function
+         should automatically select this option.  Say N unless you
+         are compiling an out-of tree driver which tells you that it
+         depends on this.

+         This option enables a simple self-test of the glob_match
+         function on startup.  It is primarily useful for people
+         working on the code to ensure they haven't introduced any
+         regressions.
+
+         It only adds a little bit of code and slows kernel boot (or
+         module load) by a small amount, so you're welcome to play with
+         it, but you probably don't need it.
